No, but I think the answer given was that the previous major shutdown was in the early seventies, and there was a backup reactor, the NRX, available at that time. So it didn't create the global shortages we've seen recently with the shutdown of the NRU—or, actually, with the shutdown of the Petten reactor last year. Notwithstanding the efforts of the NRU to ramp up production, there was still a significant impact on the global marketplace.
But prior to 2007, which I think is what you referred to, I'm not aware of any incidents of the kind we've experienced in the last few years. There have been periodic shutdowns of other reactors in the world over the last five years, not just in Canada, which have led to a tight supply situation on occasion.
